How to Find the Best Commercial Solar Companies in Phoenix AZ

With the rising cost of energy, businesses in Phoenix, AZ are turning to renewable sources like solar for a more sustainable and reliable power solution. Interestingly enough, finding the best commercial solar companies in Phoenix can be a tough task, even harder than choosing the best solar panels!

To find the best, it is important to do your research on what is available and weigh up multiple factors such as quality of service, pricing, customer reviews and warranties.

In this guide, we will provide helpful advice on how to find the best solar company in Phoenix Arizona that meets your individual needs.

Checklist to Finding the Best Commercial Solar Installers in Phoenix Arizona

Finding the best commercial solar companies in Phoenix can be confusing, particularly in the state of Arizona, which ranks 5th in the USA for solar installations.

Testimonials and Reviews

Looking at the testimonials and reviews of all the companies can be an option to find the best companies.

However, relying on reviews only is a bad idea as companies may have bought the reviews. So, the best option is to do thorough research.

Even better than online reviews… References!

Anyone can go on and leave a review on a website, but having an actual signed letter from a customer is a solid way to ensure that the solar company you’re considering is the real deal.

Check with others

Another option would be to ask other businesses that have solar panels. This lets you know which solar companies are popular with other commercial businesses and how good or bad their experiences have been.

Taking reviews from fellow business owners also can help you know a lot about the various commercial solar companies in Phoenix for you to consider.

Business owners can also talk with their friends and family members to see if they know any good solar companies that provide commercial solar panels. If one of your relatives has solar panels installed in their home, chances are their solar company may also provide commercial solar, or know of a company that they recommend.

What to look for when hiring a commercial solar contractor in Arizona

After you’ve compiled a list of a few different solar installers to look further into, here are the next steps of what to look for:


After listing down a handful of solar companies, you should start checking whether they are properly licensed.

A license from State License Board is a minimum requirement for any solar company. If a solar company does not have a valid license from Arizona, it is best to avoid that company.

The Arizona Registrar of Contractors does not provide any particular license for solar companies. In the state of Arizona, the license to install solar equipment is covered by the R-11 and C-11 electrical licenses. A commercial solar company needs to have the C-11 electrical license to provide service.

Negative Reviews

Next, it is time to check different review sites to look for any negative reviews about the filtered solar companies.

Negative reviews show how the company provides its service, its faults, and most importantly, its behavior toward the customers.

Also, if a company does not answer back to negative reviews, it shows that the company does not care about the opinion of its customers. So, look for the red flags to find out how a company really is.

In-person Check

Once you’ve narrowed your list of commercial solar companies down to a few good options, it’s time to visit their offices in person. This will give you a chance to meet the staff, see the facilities, and ask any questions you may have about the services they offer. With this information in hand, you’ll be able to make an informed decision about which company is right for your needs.

You need to talk frankly with the solar company to know in detail about their service. You can also ask questions about their previous negative reviews.

In addition, you can check the solar panels and the photos of the solar company’s previous projects.

If everything works out well, check if the paperwork they provide shows the same thing as the company said. Check if the paperwork is clear about the installation process, the upfront cost, the warranty, and the incentives.

Also, make sure the installer visits your company building in person instead of relying on pictures. An in-person site visit shows the professionalism of a solar company.

If everything goes smoothly, you will end up with the best commercial solar company in Phoenix, AZ, which may not be who looks best “on paper”, but who you feel most comfortable and confident with!
